c语言万年历.doc

C语言课程设计内容： 课程设计题目：万年历 功能如下：1、查询某年某月某日是星期几 2、打印某年的某月的全月日历 3、打印某年的全年日历 4、退出 具体要求： （1）在住菜单中输入1后，显示：“请输入年月日（XXXX,XX,XX）” 运行后输出：XXXX年XX月XX日是星期X，是否继续查询（Y/N）？ 如果输入Y，则重新显示“请输入年月日（XXXX,XX,XX）”，否则回到主菜单. （2）在主菜单中输入2后，显示：“请输入要打印的月份（XXXX）” 运行后输出X月的日历，格式为： XXXX年XX月 S M T W T F S X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X （3）在主菜单中输入3后，显示：“请输入要打印的年份（XXXX）” 运行后输出XXXX年的日历， XXXX X（月数） S M T W T F S X X X X X X X X X X X X X X X X X X X X X X X X X X X X x x S M T W T F S X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X 运行完成后显示：“是否继续打印（Y/N）？” 如果输入Y，则重新显示“请输入要打印的年份（XXXX）”，否则回到主菜单。 （4） 在主菜单中输入4后，显示：“是否要真的退出（Y/N）？” 如果输入Y，结束程序运行，否则重新显示主菜单。#include #include typedef struct int year; char month; char day;*DATE;DATE NewDate(void);int DestroyDate(DATE date);int DaysAMonth(DATE date);int CheckDate(DATE date);int SetDate(DATE date,int year,int month,int day);int GetWeek(DATE date);int QueryDay(void);int ShowMonth(DATE date);int QueryMonth(void);int QueryYear(void);int ConfirmExit(void);int Calendar(void);int main() if(Calendar() return 0; else return 1;DATE NewDate(void) DATE date; date=(DATE)malloc(sizeof(*date); return date;int DestroyDate(DATE date) if(!date) return 0; free(date); return 1;int DaysAMonth(DATE date) int days; if(!date) return 0; switch(date-month) case 1: case 3: case 5: case 7: case 8: case 10: case 12: days=31; break; case 4: case 6: case 9: case 11: days=30; break; default: days=0; break; if(date-month=2) if(date-year%4=0 & date-year%400!=0 | date-year%400=0) days=29; else days=28; return days;int CheckDate(DATE date) if(!date) return 0; if(date-monthmonth12) return 0; if(date-daydayDaysAMonth(date) return 0; return 1;int SetDate(DATE date,int year,int month,int day) if(!date) return 0; date-year=year; date-month=month; date-day=day; return CheckDate(date);int GetWeek(DATE date) int year,month,day; if(!date) return 0; year=date-year; month=date-month; day=date-day; if(month=2) month+=12; -year; return (day+2*month+3*(month+1)/5+year+year/4-year/100+year/400)%7+1;int QueryDay(void) DATE date; char cont; int year,month,day; static char *week=星期一,星期二,星期三,星期四,星期五,星期六,星期日; if(!(date=NewDate() return 0; do printf(请输入年月日（XXXX,XX,XX）); scanf( %d, %d, %d,&year,&month,&day); if(SetDate(date,year,month,day) printf(%4d年%2d月%2d日是%s，是否继续查询（Y/N）？, year,month,day,weekGetWeek(date)-1); scanf( %c,&cont); else printf(日期输入错误！n); while(cont=Y | cont=y); DestroyDate(date); return 1;int ShowMonth(DATE date) int startweek; int days; int i; if(!date) return 0; startweek=GetWeek(date); days=DaysAMonth(date); printf( S M T W S F S n); startweek=startweek%7; for(i=0;istartweek;+i) printf( ); for(i=1;i=days;+i) printf( %2d ,i); startweek=(startweek+1)%7; if(startweek=0) printf(n); if(startweek!=0) printf(n); return 1;int QueryMonth(void) int year,month; DATE date; if(!(date=NewDate() return 0; printf(请输入要打印的月份（XXXX,XX); scanf( %d, %d,&year,&month); if(SetDate(date,year,month,1) printf(%4d年%2d月n,year,month); ShowMonth(date); else printf(月份输入错误！n); DestroyDate(date); return 1;int QueryYear(void) int year; int month; DATE date; char cont; if(!(date=NewDate() return 0; do printf(请输入要打印的年份（XXXX）); scanf( %d,&year); printf(%4d年n,year); for(month=1;month=12;+month) SetDate(date,year,month,1); printf(%2d月n,month); ShowMonth(date); printf(是否继续打印（Y/N）？); scanf( %c,&cont); while(cont=Y | cont=y); DestroyDate(date); return 1;int ConfirmExit(void) char exit; printf(是否要真的退出（Y/N）？); scanf( %c,&exit); if(exit=Y | exit=y) return 1; else return 0;int Calendar(void) int menu=1; int tmp; do switch(menu) case 1: printf(n |1 查星期| |2 月日历| |3 年日历| |4 退出|:); scanf( %d,&tmp); switch(tmp) case 1: menu=11; break; case 2: menu=12; break; case 3: menu=13; break; case 4: menu=14; break; default: printf(选择有误！n); break; break; case 11:
